Water quality composite purifier for aquaculture water and preparation method thereof

Abstract

The invention discloses a water quality composite purifier for aquaculture water. The water quality composite purifier is prepared by pelletizing or tableting after uniformly mixing the following rawmaterials in parts by weight: 10-15 parts of ferrate, 10-15 parts of potassium permanganate, 15-20 parts of potassium hydrogen persulfate complex salt, 20-25 parts of nano oxide, 30-40 parts of sodiumchloride, 10-15 parts of magnesium salt, 2-5 parts of sodium dodecyl benzene sulfonate, 2-3 parts of pregelatinized starch, and 1-3 parts of polyethylene glycol-6000. The purifier can be rapidly dispersed at the bottom of a pool. Through a superoxide and micelle cage complexing principle, heavy metal ions, organic matters and other harmful substances can be destroyed by oxidation and complexed ina cage type, and oxygen is provided to the water. The invention further provides a preparation method for the water quality composite purifier. The method is simple and easy to operate, and easy to large batch production.

Description

technical field [0001] The invention belongs to the field of water quality purification, and in particular relates to a water quality composite purifier for aquaculture water bodies and a preparation method thereof. Background technique [0002] China is a big aquaculture country. Because of the large area of ​​aquaculture, the pollution of aquaculture water is also purposeful. Research shows that in the current aquaculture process, due to the low utilization rate of bait, organic matter such as residual bait and feces continue to accumulate. Although the water body Has a certain self-purification ability, but pursues high-yield and high-density breeding, [0003] It often causes the surge of ammonia nitrogen and sulfide in the water body, hypoxia and eutrophication of the water body, and the enrichment of C, N, and P in the sediment and the reduction of redox potential, resulting in excessive ammonia nitrogen and nitrite content. It may lead to the direct death of farmed a...

Problems solved by technology

Although the treatment effect of these chemical preparations is very good, they have limitations and pertinence: coagulants can only coagulate and have a long action period, flocculants can only flocculate, and the amount of oxidant has no effect, and excessive amount will cause phytotoxicity. Although there is no harm, but the amount used is large, and the oxygenating agent can only increase oxygen, etc.
